RIM-TOOL.

To all whom it may concern:

Be itknown that 1, Moses MILTON HER- MAN, a citizen of the UnitedStates, and a, resident of Dani-ills, in the county of Pith sylvnnia andState of Virginia, have inrented a certain'new and useful Improvement inRim-Tools, of which the following is a specification.

My present invention relates generally to tools for reducing the normalcircumference of split demountsble rims of various types now in commonuse, and more particularly to a tool of the nature described and claimedin my Patent Number 1,133,139, which was granted March 23, 1915.

The object of my present invention is to provide a toolineludinglclamping members, having engagement wit portions of the innerperiphery of a rim as well as the side edges thereof, withoutnecessitating particular formation of the rim, and permitting the tooltobe utilized in connection withany rim of the demountsble type.

In carrying out my present invention I preferably employ the structureof clamping 'member as shown in the accompanying drawing in Which-Figure 1 is a perspective view'illustrating reduced in circumference topermit of t e withdrawal of its tire therefrom, and illustrating thepractical application of my invention thereto. Fig. 2 is a longitudinalsection through a portion of the rim and one of the clamping membersengaged therewith, and Fig. 3 is a transverse section taken therethroughsubstantially on line 3-3 of Fig. 2.

Referring now to these figures, a tire A is shown upon a split rim B ofthe demountuble'type, at spaced points in connection with the latter ofwhich, the clamping nembers forming part of my invention, are engaged,each of these clamping member-s neluding a body plate C, which inaccordance with my present invention, has its outer face concsved toprovide projectin transversely extending engaging edges C adapted topositively engage the inner peripheral surface of the rim B innon-slipping relation. Each of the body plates C. as clearly seen, isalso provided with a transverse opening. through which extends uclumping bolt F, havinga ri irl,rimnping pic-co l at one end, andextrn-...ng loosely through a movable clamping piece i at its oppositeend. the

latter end o the bolt been; threaded for the 4 reception of a wing nut F3 by. which the clamping. p eces F and F which are en- 'gageable withthe opposite side edges of the rim B,as best seen in Fig. 3, are movedrelutiyely to one another in order to firmly embrace .the' said sideedges of the rim and thus maintain .the body plate C snugly against therim and insure positive engagement of its engaging edges C mentioned.

The clamping members are connected by connecting rods D and D, the outerends of which are hingedly connected at c tothe inner portions of thebody plates C, and the inner ends or". which connecting rodsD and D areconnected b. means of a turnbuckle E providing for t eir relativeadjustment in order to move the clamping members toward and away fromone nnother and thus reduce the rim circumierentially prepsratorv towithdrawing the tire A therefrom.

ment seems certain of the rojectin'g. edges C and the inner periphery ofthe rim.

Clamping members so constructed and relatively engaged with spacedportions of the rim, thus obviate any necessity of par- I, as aboveticulnr formation of a rim, such'as for instance the provision ofprojections or recesses in the rim, as in my application above referredto, and at the same time are effectively prevented from accidenteldisplacement 'circumferentially of the rim-from the particular point towhich they may be applieu. i

In reducing the circumference of the run I topermit of the removal o thetire, as before stated, the turnbuckle E is manipulated to draw theconnecting rods D and D to ard one another ti'illS moving the clampingmembers reiativ'ely to one another and the portions of the-rim to whichthey are attached. 7

I cluini:

1. A rim tool of the character described comprising a pair of clampingmembers, each of which consists of a body late having transverseengaging edges prQ ecting beyond its outer face to positively engage theinner periphery of a rim in non-slippim relation, clamping piecescarried by each of said clamping members and for detachable engagementwith the/side edges of therim,

and adjustable counecticnsbetween the said clampmgmembers. V

' 21A rim tool of. the charact'er described 'fco n'p'rising a pair-ofclamping iiieinbers,

each of which is provided with means for detachablyen'ga-ging the sideedges of a rim, and'each of which is provided without-'va'rdlyprojecting transversely. extendingadjus'ta'ble connectipnsbetweeir the said idg'mpirig members.

- comprising 3. A rim tool of the character described a pair of clanping members, each of which consists of a body plate, the outer face ofwhich is concaved to provide transi'erse engaging edges at the 'upperand lower ends of the plate, projecting beyond its said outer-face topositively engage the inner 'periphery' of a rim in non-slippingrelation, clamping pieces-carried by each of said clampin members "fordetachably engaging the side edges of the-rim, and adj us t, ablecoimectibns between 4 said clamping members; I i
